NeuroMag Designs for Health | Brain Magnesium Guide

Explore NeuroMag Designs for Health featuring Magtein® Magnesium L-threonate. Learn how this brain-focused Magnesium supports cognitive function and memory.

Overview

NeuroMag Designs for Health: Brain-Focused Magnesium Support

NeuroMag™ is a specialized Magnesium supplement built around the patented mineral Magtein® — Magnesium chelated to threonic acid (Magnesium L-threonate). Unlike many conventional Magnesium forms, Magnesium L-threonate is a highly bioavailable chelated form that has the potential to cross the blood-brain barrier, making it uniquely suited for cognitive and neurological support.

Research demonstrates that elevating brain Magnesium content through supplementation with Magnesium L-threonate may be a useful strategy to support cognitive abilities and healthy memory. NeuroMag Designs for Health delivers 145 mg of Magnesium (from 2 g of Magtein® Magnesium L-threonate) per serving in a convenient 3-capsule daily dose.

This formula is vegan, vegetarian-friendly, and made without GMOs, soy, dairy, or gluten — delivering clean, targeted brain support in 90 capsules per bottle.

Why It Matters

Why Brain Magnesium Matters for Cognitive Health

Magnesium is a cofactor in more than 300 enzyme systems that regulate diverse biochemical reactions in the body, yet emerging evidence confirms that nearly two-thirds of the population in the western world is not achieving the recommended daily allowance for Magnesium. As we age, Magnesium absorption and retention can decrease, making older adults especially susceptible to deficiency.

In the brain, Magnesium serves as a voltage-dependent blocker of NMDA receptors, a regulator of synaptic plasticity, and a neuroprotective agent against excitotoxicity and neuroinflammation. Brain Magnesium levels decline with age and are reduced in patients with neurodegenerative conditions. Research suggests that not all forms of Magnesium are equally effective at reaching the brain — Magnesium L-threonate has gained attention specifically for its potential to cross the blood-brain barrier.

Research has found that Magnesium threonate may be more effective in crossing the blood-brain barrier compared with other supplemental forms, and that elevating brain Magnesium content may be a useful strategy to support cognitive abilities, decrease common age-related memory decline, and serve as a supportive focus supplement.

What's inside

Key Ingredients

Magnesium (from 2g Magtein® Magnesium L-Threonate) — 145 mg
Magnesium is the fourth most abundant cation in the human body and a critical cofactor in hundreds of enzymatic reactions that regulate energy metabolism, neuromuscular function, cardiovascular health, bone integrity, immune defense, and psychological well-being. In this formula, Magnesium is delivered as Magtein® Magnesium L-threonate — a patented, highly bioavailable chelated form that has gained attention for its potential to cross the blood-brain barrier. Magnesium L-threonate has been shown to be superior in repleting Magnesium in the body compared with other forms. In the brain, Magnesium serves as a voltage-dependent blocker of NMDA receptors, a regulator of synaptic plasticity, and a neuroprotective agent against excitotoxicity and neuroinflammation. Multiple RCTs demonstrate that Magnesium L-threonate supplementation may support episodic and working memory in adults; a 12-week RCT in older adults with mild cognitive impairment found that Magnesium L-threonate produced a cognitive score improvement equivalent to approximately 9 years of cognitive rejuvenation. Studies suggest Magnesium supports brain health by regulating NMDA receptor plasticity and synaptic density — processes central to memory encoding and consolidation. A 2024 systematic review and meta-analysis found consistent associations between serum Magnesium levels and dementia risk, and a study of 2,466 adults aged 60+ found higher Magnesium levels associated with significantly better attention and memory. Magnesium also plays a well-documented role in neurotransmitter balance, serving as a cofactor in dopamine synthesis and a physiological blocker of NMDA glutamate receptor channels. Research suggests it supports inhibitory-excitatory neurotransmitter balance and may promote healthy nervous system function. Magnesium modulates the HPA axis, supports GABA receptor function, and may support the gut-brain connection. A 2024 PMC review identifies Magnesium inadequacy as a contributor to accelerated aging and proposes maintaining optimal Magnesium levels as a strategy for promoting healthy aging, with Magnesium directly linked to all 12 recognized hallmarks of aging.
Dicalcium Phosphate
Dicalcium phosphate is a Calcium salt commonly used as an excipient in supplement manufacturing. Calcium is the most abundant metal in the human body, with more than 99% stored in bone as hydroxyapatite. Calcium plays essential roles in cell signaling, neurotransmission, muscle contraction, and bone metabolism. In this formulation, dicalcium phosphate serves as a processing aid to support capsule integrity and consistent delivery of the active Magnesium L-threonate.

Who May Benefit from NeuroMag

NeuroMag Designs for Health is formulated for adults seeking targeted brain and cognitive support. It may be particularly relevant for individuals concerned with supporting healthy memory, maintaining cognitive abilities, and addressing common age-related changes in mental sharpness.

Because Magnesium absorption and retention can decrease with age — and older adults are more susceptible to Magnesium deficiency — this formula may be especially appropriate for those in midlife and beyond who want to proactively support brain health. Research suggests that elevating brain Magnesium may be a useful strategy for supporting cognitive abilities and decreasing common age-related memory decline.

NeuroMag is also suitable for those following vegan, vegetarian, gluten-free, dairy-free, or soy-free dietary preferences, as it is made without GMOs, soy, dairy, and gluten.

FAQ

Frequently asked questions

What makes NeuroMag different from other Magnesium supplements?

NeuroMag uses the patented mineral Magtein® — Magnesium chelated to threonic acid (Magnesium L-threonate). This highly bioavailable form has the potential to cross the blood-brain barrier, unlike many conventional Magnesium forms. Research has found that Magnesium L-threonate may be more effective in reaching the brain and has been shown to be superior in repleting Magnesium in the body compared with other forms.

How does Magnesium L-threonate support memory and cognitive function?

Research demonstrates that elevating brain Magnesium content through supplementation with Magnesium L-threonate may support cognitive abilities and healthy memory. The mechanistic basis involves Magnesium's regulation of NMDA receptor plasticity and support for synaptic density — processes central to memory encoding and consolidation. Multiple RCTs suggest that Magnesium L-threonate supplementation may improve episodic and working memory in adults.

Is NeuroMag suitable for vegans and those with dietary restrictions?

Yes. NeuroMag is vegan and vegetarian-friendly. It is made without GMOs, soy, dairy, and gluten, making it suitable for individuals following a wide range of dietary preferences.

How much Magnesium does each serving of NeuroMag provide?

Each 3-capsule serving provides 145 mg of Magnesium from 2 g of Magtein® Magnesium L-threonate. The bottle contains 90 capsules, which provides a 30-day supply at the recommended daily serving.

Can Magnesium supplements interact with medications?

Several medications can interact with Magnesium, including diuretics, proton-pump inhibitors, bisphosphonates, tetracycline and quinolone antibiotics, and gabapentin. For example, Magnesium can form insoluble complexes with certain antibiotics, and some diuretics can increase Magnesium loss. If you are taking any medications, consult your health-care practitioner before starting supplementation.

Why is brain Magnesium important as we age?

Brain Magnesium levels decline with age, and Magnesium deficiency is associated with reduced cognitive function, neuroinflammation, and impaired stress responses. A 2024 review identifies Magnesium inadequacy as a contributor to accelerated aging, linking it to all 12 recognized hallmarks of aging. Research suggests that maintaining optimal brain Magnesium levels may be a useful strategy for supporting cognitive abilities and decreasing common age-related memory decline.
